The people here have hands down the best teeth I've seen anywhere. Keep in mind dental care is rare - these teeth are naturally straight, big and beautiful. I'm reminded of the work of Weston Price, the dentist who traveled for 10 years studying the best teeth in the world and their correlated diets. The Indonesians are one of the people he studied- they have wide arches, virtually no cavities, straight pearly whites. Their diet is very high in coconut, veggies, rice, fruits, fish and some meat. They eat little wheat, little dairy, and little refined foods, including sugar. The evenness of the bottom of their teeth is due to filing- an adolescent rite of passage.
